Career
He works in probability theory, specializing in interacting particle systems He has contributed to numerous areas of probability theory, including subadditive ergodic theory, random graphs, renewal theory, and is best known for his pioneering work on interacting particle systems, including the contact process, the voter model, and the exclusion process. His two books in this field have been influential.
Tom Liggett was the managing editor of the Annals of Probability from 1985–1987.
He held a Sloan Research Fellowship from 1973–1977, and a Guggenheim Fellowship from 1997–1998. He was the Wald Memorial Lecturer of the Institute of Mathematical Statistics in 1996, and was elected to the National Academy of Sciences in 2008.
More recently, he has been elected to the American Academy of Arts & Sciences in 2012, and in 2012 he also became a fellow of the American Mathematical Society. He graduated from Oberlin College in 1965, where he was influenced towards probability by Samuel Goldberg (b 1925), an ex-student of William Feller.
He moved to Stanford, taking classes with Kai Lai Chung, and writing a Doctor of Philosophy thesis in 1969 with advisor Samuel Karlin on problems associated with the invariance principle.
He joined the faculty at University of California, Los Angeles in 1969, where he has spent his entire career since.
